Abstract
Image recording materials, especially photothermographic light-sensitive image recording materials, that comprise a compound of formula (1) to acquire excellent image storage stability: wherein X1 and X2 each represent a halogen atom; X3 represents a hydrogen atom, a halogen atom or a univalent substituent group; L represents a divalent organic group; Y represents a divalent organic group containing a hetero atom, or a single bond; and Z represents an acidic functional group or a salt thereof.
Claims12
An image recording material comprising a support and a constituent layer(s) comprising at least (a) a heat-sensitive imaging layer containing a light-insensitive silver salt of an aliphatic carboxylic acid having 10 to 30 carbon atoms, a reducing agent of said light-insensitive silver salt and a binder or (b) a light-sensitive imaging layer containing a light-sensitive silver halide, light-insensitive silver salt of an aliphatic carboxylic acid having 10 to 30 carbon atoms, a reducing agent of said light-insensitive silver salt and a binder, wherein the image recording material comprises a compound represented by formula (1) in at least one constituent layer:
- wherein X1 and X2 each represent a halogen atom;
- X3 represents a hydrogen atom, a halogen atom or a univalent substituent group selected from the group consisting of 1-30C alkyl groups, 6-30C aryl groups, 2-30C alkenyl groups, 2-30C alkynyl groups, a nitro group, a cyano group, a hydroxyl group, a carboxyl group or salts thereof, a sulfo group or salts thereof, an amino group, 1-30C acylamino groups, 1-30C alkylsulfonyl groups 6-30 arylsulfonyl groups, 1-30C alkylsulfonylamino groups 6-30 arylsulfonylamino groups, unsubstituted or substituted carbamoyl groups, unsubstituted or substituted sulfamoyl groups and heterocyclic groups;
- L represents, an arylene group;
- Y represents SO2, or a single bond;
- and Z represents an acidic functional group or a salt thereof.
